Either high con or full con are viable. Then get all the damage in weapon, preferably trans 7 or higher.
Youll still be missing from time to time but most of time you can hit them. Block seems like the issue with high con or full con. If youre fighting with high block chars, probably 30-60% of the time youll get blocked.
Pros of high con in PVP:
Better survivability
2 HP pots scale with your total HP so you can regen quite alot. (i regen 6k per pot then 1k per tick)
For dragoon i think high STR is good, then use your range advantage (play like an archer). Since this build cant tank, however with reduced dethrone CD, you can pretty much spam dethrone 3-6 times per match.
Lancer/murmillo are good with high con.
For some reason, Corsair 3 pistol range is quite deadly. Probably the only swordie pvp that can benefit with high dex, assuming pistol scale with dex because i havent tried dex scaling with corsair yet (i tried it with full con). Corsair 3 then Shinobi. Invi-pistol shot.
Evasion and block are the same calculation with crit rate i think. It will only be good at 1.4k+. 1k evasion seems very hard to achieve. Block can go as high as 1.5k so blocking is still prominent, until you saw a SR 3 full dex with 1.3k block pen.
